You don't have to declare it as a MvL> method argument, though.Modula-3 was mentioned in another post.There is a reason other than simple clarity (I like using an explicitself) for this approach. Python's rules for local variables wouldinterfere with attribute access. Since Python eschews variabledeclarations, any assignment to a name inside a code block makes thatname a local variable. By this rule alone, there would never by a wayto assign to an instance variable :-). You'd need a mechanism likethe global statement to say "This name isn't a local."We had an opportunity to change the attribute access approach whennested scopes were introduced, but we went out of our way (well, sortof) to preserve the self.attr approach.Jeremy
